Questions
A uniform rope of length and mass hangs vertically from a rigid support. A block of mass is attached to the free end of the rope. A transverse pulse of wavelength is produced at the lower end of the rope. The wavelength of the pulse when it reaches the top of the rope is . The ratio is
detailed solution
Correct option is D
Wavelength of pulse at the lower end λ1∝ velocity v1=T1μ Similarly, λ2∝v2=T2μ∴λ2λ1=T2T1=m1+m2gm2g=m1+m2m2Similar Questions
